The advancement from Tier Three to Tier Four for a Martial Artist is a process of opening the Sea of Qi and refining True Qi.
Stepping from Tier Four to Tier Five requires transforming all True Qi into True Essence.
This is known as Qi Condensation and Yuan Transformation.
Although both Tier Four and Tier Five belong to the Qi Entry Realm, they are considered a promotion rather than breaking through a realm, but the difficulty is not low at all.
A martial artist's own talent, root bone, comprehension, the cultivation technique practiced, and even the resources consumed on a daily basis are all closely related, and mere effort is not enough.
It's not been long since Zhang Yuan opened his Sea of Qi.
The fact that he can condense Qi into Yuan so quickly is inseparable from the opportunities he has encountered.
